Panoramic 3-Panel Aluminium Sliding Window | H1200 x W2400

The H1200 x W2400 panoramic three-panel aluminium sliding window provides an expansive 2.4-metre view while delivering exceptional airflow control. Featuring a wide central fixed pane and two independently operable sliding end panels, this unit is the perfect solution for large living areas, dining rooms, and alfresco serveries. You get a massive, unobstructed picture window right in the middle, alongside flexible ventilation on both sides to keep your home cool and comfortable.

The Advantage of a 2.4 Metre Span

Framing a new home or planning a major renovation requires smart dimensional choices. A width of 2400mm is a sweet spot in Australian residential construction. It aligns perfectly with standard building materials and timber stud spacings. This means your builder can install this large window without requiring excessively complex structural steelwork.

When a builder prepares a wall for a 2.4-metre window, they must install a substantial lintel above the opening to carry the roof load. Because our aluminium frames are incredibly rigid and perfectly square, they make the installation process straightforward. Your carpenter can pack and level the frame quickly, securing it firmly into the timber or steel studwork before applying the exterior flashing.

At 1200mm high, this rectangular format provides a generous vertical viewing area. It leaves plenty of usable wall space directly underneath for your living room furniture, radiator heaters, or kitchen cabinetry.

The three-panel configuration completely changes how a wide window operates. If you split 2400mm into just two panels, you end up with two massive 1.2-metre glass squares. Those large squares are heavy and visually blocky. By moving to a three-panel layout, we place a large fixed picture window directly in the centre. We then flank it with two narrower sliding sashes on the left and right. This gives you a crystal clear panoramic sightline right where you look the most. When you need fresh air, you simply glide open the outer panels. You can open one side to catch a gentle cross breeze, or slide both ends completely open to cool down a hot room in minutes.

Room by Room Application Guide

Builders and homeowners specify this panoramic 2.4-metre frame to make a serious visual impact. It completely transforms dark rooms into bright, welcoming spaces.

Open Plan Living Areas Replacing a solid wall with a 2.4-metre glass window creates a brilliant visual connection to your backyard. Because you can open both ends of the window simultaneously, it excels at creating cross ventilation. The system draws fresh air straight across your lounge room. This natural cooling method drastically reduces your reliance on expensive air conditioning during summer.

Alfresco Serveries This specific three-panel configuration is highly popular for indoor and outdoor kitchen areas. If you install this window flush with your kitchen benchtop, it functions as a massive servery. You can slide the outer sashes open and pass plates, drinks, and food directly out to your patio area. The wide central fixed pane protects your internal prep area from the wind while keeping you visually connected to your guests outside.

Master Suites Large bedrooms need plenty of natural morning light to feel inviting. This window floods the space with sun while giving you total control over the overnight temperature. You can crack the outer windows slightly for a cool breeze. The key-lockable handles keep the sashes securely fixed in place, meaning you can sleep comfortably without worrying about intruders.

Customising Your Glazing and Finish

A window of this size creates a large thermal bridge. The type of glass you select will heavily dictate how hot or cold your room feels throughout the year. We build every window to order so you can choose the exact thermal performance your location requires.

Standard Clear glass is a cost effective choice for heavily shaded patios or southern facing walls. If this window faces the harsh western sun, standard glass will trap the heat inside. For exposed locations, we strongly advise upgrading to Low-E glass or a Grey Tint. Low-E glass features a microscopic coating that actively reflects radiant heat. It bounces summer heat back outside and retains your internal heating during winter.

For the highest level of energy efficiency, you need our Double Glazed units. Double glazing traps an insulating pocket of argon gas between two separate glass panes. This setup creates a massive thermal barrier that significantly lowers your power bills while simultaneously blocking out loud traffic noise. Our glass options also help you meet mandatory energy efficiency targets. Modern homes must comply with the National Construction Code, which often requires specific Window Energy Rating Scheme (WERS) performance levels. By selecting Low-E or double glazed units, you significantly improve the insulation value of your home.

We finish all our aluminium frames in a highly durable powder coating. This baked finish actively resists fading, chalking, and coastal corrosion. Pearl White is a classic, heat reflective choice that suits traditional Australian homes. Custom Black provides a striking, high contrast border that frames your outside view perfectly. Our Custom Colour service ensures your new window blends into your specific architectural plans.

Internal Security and External Screening

Sliding windows feature screens mounted on the outside of the track. Because the central pane is fixed, you only need to screen the two outer sliding sections. This creates a massive aesthetic advantage. The large central picture window remains completely free of mesh, giving you a clear, unobstructed view of your garden.

Our window profiles include integrated external tracks to hold these screens securely. A standard Flyscreen keeps mosquitoes out during summer evenings. If you want true peace of mind, upgrade to our Stainless Steel Security Screens. This heavy-duty woven mesh resists knife attacks and forced entry attempts. It allows you to leave both sides of your panoramic window wide open on a hot night while keeping your family totally secure.

Built to Meet Australian Standards

The Australian climate destroys cheap building materials very quickly. We build our products to survive extreme heatwaves, driving rain, and strong winds without warping or leaking. Every aluminium window we manufacture complies strictly with AS 2047 building standards. This certification means your specific window design has passed rigorous laboratory testing for structural deflection, operating force, and water penetration resistance.

Whether your job site is located in Sydney, Melbourne, Brisbane, Perth, Adelaide, or a regional centre, we transport your custom windows safely to your door. You are investing in heavy-duty products engineered by locals who understand exactly what the Australian environment demands.

Frequently Asked Questions

Is a 2.4-metre wide window difficult to operate? Not at all. We use premium commercial grade bottom rollers on the sliding sashes. The weight of the moving glass rests entirely on the bottom track, ensuring a smooth, quiet glide. You can open and close the sashes with very little physical effort.

How do the screens work on a three-panel window? The screens fit directly into the external track on the far left and far right sides of the window. They cover the operable sliding sections only. The central fixed pane does not require a screen, which ensures your panoramic view remains perfectly clear.

What is the lead time for this custom size? We build this large architectural unit entirely to order based on your specific colour, glass, and screen choices. Our standard manufacturing lead time is 12 to 15 working days from the date of purchase.
